The institution of benchmarks that faithfully replicate real-world duties is crucial within the quickly creating subject of synthetic intelligence, particularly within the software program engineering area. Samuel Miserendino and associates developed the SWE-Lancer benchmark to evaluate how properly giant language fashions (LLMs) carry out freelancing software program engineering duties. Over 1,400 jobs totaling $1 million USD had been taken from Upwork to create this benchmark, which is meant to guage each managerial and particular person contributor (IC) duties.
What’s SWE-Lancer Benchmark?
SWE-Lancer encompasses a various vary of duties, from easy bug fixes to advanced function implementations. The benchmark is structured to supply a practical analysis of LLMs by utilizing end-to-end exams that mirror the precise freelance evaluate course of. The duties are graded by skilled software program engineers, guaranteeing a excessive commonplace of analysis.
Options of SWE-Lancer
- Actual-World Payouts: The duties in SWE-Lancer characterize precise payouts to freelance engineers, offering a pure issue gradient.
- Administration Evaluation: The benchmark chooses the very best implementation plans from impartial contractors by assessing the fashions’ capability to function technical leads.
- Superior Full-Stack Engineering: As a result of complexity of real-world software program engineering, duties necessitate an intensive understanding of each front-end and back-end growth.
- Higher Grading by way of Finish-to-Finish Assessments: SWE-Lancer employs end-to-end exams developed by certified engineers, offering a extra thorough evaluation than earlier benchmarks that trusted unit exams.
Why is SWE-Lancer Necessary?
An important hole in AI analysis is stuffed by the launch of SWE-Lancer: the capability to evaluate fashions on duties that replicate the intricacies of actual software program engineering jobs. The multidimensional character of real-world tasks isn’t adequately mirrored by earlier requirements, which often targeting discrete duties. SWE-Lancer presents a extra life like evaluation of mannequin efficiency by using precise freelance jobs.
Analysis Metrics
The efficiency of fashions is evaluated primarily based on the share of duties resolved and the overall payout earned. The financial worth related to every job displays the true issue and complexity of the work concerned.
Instance Duties
- $250 Reliability Enchancment: Fixing a double-triggered API name.
- $1,000 Bug Repair: Resolving permissions discrepancies.
- $16,000 Function Implementation: Including help for in-app video playback throughout a number of platforms.
The SWE-Lancer dataset incorporates 1,488 real-world freelance software program engineering duties, drawn from the Expensify open-source repository and initially posted on Upwork. These duties, with a mixed worth of $1 million USD, are categorized into two teams:
Particular person Contributor (IC) Software program Engineering (SWE) Duties
This dataset consists of 764 software program engineering duties, price a complete of $414,775, designed to characterize the work of particular person contributor software program engineers. These duties contain typical IC duties comparable to implementing new options and fixing bugs. For every job, a mannequin is supplied with:
- An in depth description of the problem, together with replica steps and the specified habits.
- A codebase checkpoint representing the state earlier than the problem is mounted.
- The target of fixing the problem.
The mannequin’s proposed resolution (a patch) is evaluated by making use of it to the offered codebase and operating all related end-to-end exams utilizing Playwright. Critically, the mannequin doesn’t have entry to those end-to-end exams in the course of the resolution technology course of.

SWE Administration Duties
This dataset, consisting of 724 duties valued at $585,225, challenges a mannequin to behave as a software program engineering supervisor. The mannequin is offered with a software program engineering job and should select the very best resolution from a number of choices. Particularly, the mannequin receives:
- A number of proposed options to the identical subject, taken instantly from actual discussions.
- A snapshot of the codebase because it existed earlier than the problem was resolved.
- The general goal in choosing the right resolution.
The mannequin’s chosen resolution is then in contrast towards the precise, ground-truth finest resolution to guage its efficiency. Importantly, a separate validation examine with skilled software program engineers confirmed a 99% settlement charge with the unique “finest” options.

Mannequin Efficiency
The benchmark has been examined on a number of state-of-the-art fashions, together with OpenAI’s GPT-4o, o1 and Anthropic’s Claude 3.5 Sonnet. The outcomes point out that whereas these fashions present promise, they nonetheless battle with many duties, significantly these requiring deep technical understanding and context.
Efficiency Metrics
- Claude 3.5 Sonnet: Achieved a rating of 26.2% on IC SWE duties and 44.9% on SWE Administration duties, incomes a complete of $208,050 out of $500,800 potential on the SWE-Lancer Diamond set.
- GPT-4o: Confirmed decrease efficiency, significantly on IC SWE duties, highlighting the challenges confronted by LLMs in real-world functions.
- GPT o1 mannequin: Confirmed a mid efficiency earned over $380 and carried out higher than 4o.
Complete payouts earned by every mannequin on the total SWE-Lancer dataset together with each IC SWE and SWE Supervisor duties.
Outcome
This desk exhibits the efficiency of various language fashions (GPT-4, o1, 3.5 Sonnet) on the SWE-Lancer dataset, damaged down by job kind (IC SWE, SWE Supervisor) and dataset measurement (Diamond, Full). It compares their “cross@1” accuracy (how usually the highest generated resolution is right) and earnings (primarily based on job worth). The “Consumer Software” column signifies whether or not the mannequin had entry to exterior instruments. “Reasoning Effort” displays the extent of effort allowed for resolution technology. Total, 3.5 Sonnet typically achieves the best cross@1 accuracy and earnings throughout totally different job varieties and dataset sizes, whereas utilizing exterior instruments and growing reasoning effort tends to enhance efficiency. The blue and inexperienced highlighting emphasizes general and baseline metrics respectively.
The desk shows efficiency metrics, particularly “cross@1” accuracy and earnings. Total metrics for the Diamond and Full SWE-Lancer units are highlighted in blue, whereas baseline efficiency for the IC SWE (Diamond) and SWE Supervisor (Diamond) subsets are highlighted in inexperienced.
Limitations of SWE-Lancer
SWE-Lancer, whereas helpful, has a number of limitations:
- Variety of Repositories and Duties: Duties had been sourced solely from Upwork and the Expensify repository. This limits the analysis’s scope, significantly infrastructure engineering duties, that are underrepresented.
- Scope: Freelance duties are sometimes extra self-contained than full-time software program engineering duties. Though the Expensify repository displays real-world engineering, warning is required when generalizing findings past freelance contexts.
- Modalities: The analysis is text-only, missing consideration for the way visible aids like screenshots or movies may improve mannequin efficiency.
- Environments: Fashions can’t ask clarifying questions, which can hinder their understanding of job necessities.
- Contamination: The potential for contamination exists as a result of public nature of duties. To make sure correct evaluations, looking must be disabled, and post-hoc filtering for dishonest is crucial. Evaluation signifies restricted contamination affect for duties predating mannequin data cutoffs.
Future Work
SWE-Lancer presents a number of alternatives for future analysis:
- Financial Evaluation: Future research may examine the societal impacts of autonomous brokers on labor markets and productiveness, evaluating freelancer payouts to API prices for job completion.
- Multimodality: Multimodal inputs, comparable to screenshots and movies, should not supported by the present framework. Future analyses that embody these parts could supply a extra thorough appraisal of the mannequin’s efficiency in sensible conditions.

Conclusion
SWE-Lancer represents a big development within the analysis of LLMs for software program engineering duties. By incorporating real-world freelance duties and rigorous testing requirements, it gives a extra correct evaluation of mannequin capabilities. The benchmark not solely facilitates analysis into the financial affect of AI in software program engineering but additionally highlights the challenges that stay in deploying these fashions in sensible functions.
